Definitions
- the invention relates to a circuit arrangement for control protection in the control circuit of the contactor a controllable switching element of a control voltage source, a measuring resistor and the contactor coil are in series and a starting current control circuit tapping the voltage across the measuring resistor is provided.
- Protection control circuit 34 includes a rectifier block 7 of a control voltage source and connected in series a contactor coil 1, a switching element 2 and a measuring resistor 3.
- a starting current control circuit 24 connected via a logic element 8
- connected to the switching element 2 by means of a driver stage 26 is in operative connection with the switching element 2 stands.
- a Setpoint device 25 for providing a reference voltage switched on.
- the logic element 8 is also with a programmable control device 27 and one mechanical actuator 28 connected.
- the logic element 8 from a voltage form stage 31 either directly or with a timing device 32 a pulse width modulator 33 connected thereto.
- the rectifier block 7 contains a first full-wave rectification 71 to which the control circuit 34 is connected and a second full-wave rectifier 72, which is a supply circuit for voltage form stage 31 and a freewheel control 30 feeds. Furthermore lies in this supply circuit a voltage supply device 29, the operating voltage for all those consumers of the circuit arrangement delivers, which is not fed directly from the rectifier block 7 will.
- a free-wheeling branch 4 is connected to the contactor coil 1.
- this freewheel branch 4 there are a freewheel switching element 18 and a free-wheeling diode 17 arranged in series.
- the freewheeling control 30 At the control entrance of the freewheeling switching element 18 is the freewheeling control 30 connected.
- the freewheel control 30 is with the Voltage form stage 31 in signal connection.
- the circuit arrangement acts in such a way that in the control circuit 34 a control current flows as soon as a corresponding one Control signal of a higher-level regulation to the control circuit 34 of the contactor is switched. Because the contactor coil 1 is energized, the contactor picks up. The starting current is kept constant by the fact that one of the height this starting current proportional measuring voltage across the measuring resistor 3 tapped and the starting current control circuit 24 is fed with a comparator.
- the comparator compares the measuring voltage with a reference voltage of the setpoint adjustment device 25. By adjusting the amount of Reference voltage can change the switching threshold of the comparator will.
- the selectable reference voltage corresponds the respective starting current.
- the pulse width modulator requires a large number of components, i.a. a monoflop and an oscillator as well as an RC element. With regard to a cost-effective solution, this would be an income Without the pulse width modulator, this is a considerable advantage.
- the invention is therefore based on the object of a circuit arrangement to create the above type, with few components get along and is inexpensive.
- this is achieved by a circuit arrangement of the type mentioned above, parallel to the measuring resistor a series connection from another electronic Switching element and another resistor.
- the circuit arrangement shown here largely agrees with that in the introduction to the description 2 described circuit arrangement, so that at this point only the essential to the invention Deviations are received.
- the circuit arrangement according to the invention has no pulse width modulator 33 and instead has a parallel to the measuring resistor 3 Series connection from an ohmic resistor 41 and an electronic switching element 40 provided by the timing device 32 forth is controllable.
- Independent of the pull-in or hold phase is that by the setpoint adjustment device 25 specified reference voltage in the starting current control circuit 24 always the same.
- switching element 40 e.g. a Switching transistor, the two shunt resistors 3.41 in parallel switched.
- the following explanations relate to the function of the Circuit arrangement.
- the voltage form level an image of the control voltage low level and then the mean stress value formed, which is fed to a voltage ramp. If the switch-on threshold of the voltage ramp is reached, e.g. 100 ms tightening phase via the time control device 32 initiated. This controls the logic 8 to the switching element 2 via the driver stage 26 closes.
- the switching element 40 is also e.g. a switching transistor closed, its duty cycle for the tightening phase also from the timing device 32 is specified.
